Setting the zero level for gravitational potential energy at B find the gravitat

Question

Setting the zero level for gravitational potential energy at B find the gravitational potential energy of this system when the skier is at A and then at B. Finally, find the change in potential energy of the skier-Earth system as the skier goes from point A to point B . Repeat this problem with the zero-level at point. Repeat again, with the zero level 2.00 m higher than point. Use the values to help you work this exercise. If the zero level for the gravitational potential energy is selected to be midway down the slope, 6.00 m above point B, find the initial potential energy, the final potential energy, and the change in potential energy as the skier goes from point A to B in the figure.

Explanation / Answer

The answer above is correct. you have the units wrong.

initial = 3.5868 kilojoules

final = -3.5868 kilojoules

change = -7.1736 kilojoules
